In a glass mix the baking soda, mustard, vanilla sugar. In another glass or hot water with lemon juice. Don't worry, you will not feel the taste and smell of mustard! Dry mustard makes baked goods soft, softness, pleasant texture and an amazing Golden color!

To repay the mustard mixture lemon water until frothy. By the way, this recipe for many years. My grandmother baked a cake, she's the only one, mustard and soda was quenched with brine from the pickles.

Add this mixture to the dough, add your favorite dried fruit – apricots, raisins or prunes, etc., mix well. I had the candied pumpkin, homemade.

The form for baking grease with vegetable oil, put the dough and put in preheated oven. Bake at 180 degrees for approximately 40-50 minutes. Cooking time depends on the size of the form and features of the oven. If the form is wide, the batter will be less, so the baking time will be reduced. Therefore, check the readiness for 30-35 minutes, but not before, the batter may settle.

Readiness check cake with a toothpick.

The finished cake to cool, sprinkle with powdered sugar, cut into pieces and you can warm the tea. Flavorful, tender... simply delicious dessert!
